Gyro Horizon , also called ADI (  Attitude Direction Indicator ) or  Artificial Horizon is an  important aviation instrument. It gives the  pilot an indication of the  aircraft attitude   ( Pitch and Roll ) during   flight . No aircraft can  fly without this instrument onboard.

This is how the actual ADI of the commercial jet Embraer 170 looks like. This was my inspiration for this project.

Renesas   RDK board comes with many types of sensors. I used the motion sensor (   3D accelerometer ) to sense the Roll an Pitch attitude. The 3D accelerometer  acts  as a tilt sensor , the Microcontroller analyses the values and  then  draws the output on the board LCD.

This is how the project Renesas Gyro Horizon looks like

The contrast of the LCD can be adjusted by  the included  potentiometer.

Version  2

This  version differs from Version 1  in one important feature. The first  version of the software only  indicated the Roll attitude ( Roll Right  and Roll Left ) . But this new  version senses and indicates the Roll  and also the Pitch attitude of the  aircraft ( Pitch Up [ Nose Up ] and  Pitch Down [ Nose Down ] ).

Thank you for dropping by. And good luck everyone.
